APD vs LIN: How Air Products and Chemicals and Linde Compare (2026)
Short answer
APD (Air Products and Chemicals) and LIN (Linde) are often compared because they share investment themes, but they are different businesses. Air Products and Chemicals is the third-largest industrial gases company in the world, behind Linde and Air Liquide. Linde is the largest industrial gases company in the world, providing oxygen, nitrogen, argon, hydrogen, helium, and various specialty gases to customers across manufacturing, healthcare, energy, electronics, and food processing. Neither is universally better: pick by which thesis you are expressing and what you already own. This is descriptive, not a recommendation.
What does Air Products and Chemicals (APD) do?
Air Products and Chemicals is the third-largest industrial gases company in the world, behind Linde and Air Liquide. The company provides oxygen, nitrogen, argon, hydrogen, helium, and specialty gases to industrial customers across refining, chemicals, electronics, energy, and food processing. Unlike Linde and Air Liquide, Air Products has made a particularly aggressive strategic bet on large-scale hydrogen infrastructure projects.
What does Linde (LIN) do?
Linde is the largest industrial gases company in the world, providing oxygen, nitrogen, argon, hydrogen, helium, and various specialty gases to customers across manufacturing, healthcare, energy, electronics, and food processing. The company was formed in 2018 through the merger of Linde AG (German) and Praxair (US-based), making it dual-listed but primarily reporting in USD with a Connecticut headquarters.
APD vs LIN: how do they differ?
Both fit overlapping themes, but they are not interchangeable. Air Products and Chemicals is best understood through its own drivers, and Linde through its. The useful comparison is which set of drivers and risks you want exposure to.
- APD drivers: Hydrogen mega-project execution; Activist-driven strategic refocus.
- LIN drivers: Long-term take-or-pay contract durability; Hydrogen and clean energy transition.

Linde is the largest industrial gases company in the world, providing oxygen, nitrogen, argon, hydrogen, helium, and various specialty gases to customers across manufacturing, healthcare, energy, electronics, and food processing. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is APD or LIN the better stock?
+
Walnut is informational, not investment advice. Neither is universally better; APD and LIN suit different views and risk levels. Compare what each does, how they make money, and the risks, then decide which fits your thesis and what you already own.
Should you own both APD and LIN?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both before you add the second.
What are the risks of APD vs LIN?
+
APD: Hydrogen demand may develop slower than the mega-project capital commitments require. Geopolitical risks in NEOM (Saudi Arabia) and other emerging hydrogen geographies. Capital-intensive strategy creates financial risk if returns disappoint. LIN: Capital intensity is meaningful for new gas plants. Energy costs (a major input) can compress margins if not passed through. Cyclical industries like steel and refining create some volume risk.
